Danilovskii Cordon, at light, 16– 17.09.2022 — 1♀ . Distribution. Russia (S RFE: S Khabarovskii Kr., Primorskii Kr., Sakhalin, S Kurils — Kunashir); China (NE, N, central, SW, Taiwan) Korea , Japan ( Hokkaido , Honshu, Izu Islands, Shikoku, Kyushu, Tsushima, Ryukyu Islands). Remarks. In central Japan moths appear from early May to June and from late August to October, in two generations. Larvae feed on various species of Vitaceae ( Nakajima, Yazaki 2011 ) . The subspecific specification of moths from Sakhalin and the Kurils is under the question ( Beljaev 2016 ; Beljaev, Mironov 2019 ). Viidalepp (1977 ; 1996 ) assigned moths from Sakhalin to the continental subspecies E. u. phaedropa (Prout, 1938) and moths from S Kurils — to Japanese nominative subspecies E. u. umbrosaria . But specimen from Iturup in Swedish Museum of Natural History was posted on the GBIF site ( Holston 2023 ) as E. u. phaedropa . Our specimens from Sakhalin and Kunashir, although they are noticeably smaller than the Japanese ones, are quite consistent with them in the pattern of the wings. So, we consider moths from Sakhalin and the Kurils belonging to E. u. umbrosaria .
